Abstract
A mechanical throttle control mechanism is provided for the remote control of an internal combustion engine. The mechanism comprises a speed selector arm movable between first and second limit positions, a friction lock operably associated with the speed selector arm and an arrangement of links connecting the speed selector arm to the throttle lever of the engine. The links of the mechanism are so positioned to cause a decreasing moment arm on the speed selector arm as the speed selector arm is moved from its first position toward its second position which respectively corresponds to the shut-off and full-throttle positions of the throttle lever. This arrangement reduces the need experienced heretofore for high friction disc pressure to hold the speed selector arm in a desired position between its limit positions, resulting in less disc wear and less frequent friction spring adjustment. At its second position, the selector arm is in an over-centered position which eliminates the rotational load on the friction disc and prevents the speed selector arm from slipping toward its first position.
